Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package is a legitimate observability plugin, but replay is enabled when its settings cannot be read and the README does not specifically disclose session replay. Because this captures app session activity automatically, warn users; the inspected path sends it to the local bridge rather than an unrelated collector. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-02T19:39:10.935Z - **Finished:** 2026-11-02T19:40:25.104Z - **Download time:** 770 ms - **Static scan time:** 58 ms - **AI review time:** 73340 ms - **Total time:** 74169 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Session replay is enabled by default in common configurations and records browser activity for the LensMCP bridge. - **Trigger:** A user adds the plugin and starts a Vite dev server; replay starts when no disabling setting is present and capture settings cannot be read. - **Impact:** Application session activity may be recorded and sent to the local LensMCP runtime without the README explicitly describing replay collection. - **Evidence paths:** lib/replay-setting.js, lib/plugin.js, .lpm-dependency-evidence-82ee2a56-9b55-44c6-be10-3e633fc08773/1/npm-linux/replay-source.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T19:40:25.104Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The plugin injects a replay module and supplies it with an HTTP endpoint built from the configured host and port. The default host is loopback. - **Rationale:** The package is a legitimate observability plugin, but replay is enabled when its settings cannot be read and the README does not specifically disclose session replay. Because this captures app session activity automatically, warn users; the inspected path sends it to the local bridge rather than an unrelated collector. - **Network endpoints:** http://127.0.0.1:\ ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** When LENSMCP\_REPLAY and the replay option are unset, failure to read the capture settings makes replayEnabled return true., In Vite's HTML transform, the plugin injects the replay module whenever replay is enabled., The replay recorder starts with a dynamically built HTTP endpoint using the plugin's host and port; the default host is 127.0.0.1., The package describes its normal browser event streaming, but does not disclose session replay in that description. - **Evidence against:** The package has no lifecycle scripts; it runs as a Vite plugin when configured., The bridge defaults to loopback and requires a per-server token for WebSocket connections., The package's stated purpose is frontend observability, and it documents streaming app events to LensMCP. ## Affected versions and remediation This report applies to @lensmcp/vite-plugin@1.25.51. - Review the evidence and your use of @lensmcp/vite-plugin@1.25.51 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
